Route choice dynamics after a link restoration

Abstract

ABSTRACT The original I-35W bridge collapsed on 1st August 2007, and the replacement bridge opened to the public on 18 September 2008. This study explicitly considers the day-to-day behavior of travelers after that bridge reopening. Subjects react to day-to-day travel times on a specific route according to thresholds. These thresholds help discriminate whether a travel time is within an acceptable margin or not, and travelers may decide to abandon the chosen route depending on the frequency of travel times within acceptable margins. Subjects previous experience, and perception of the alternatives, also influence their decision to abandon the chosen route.
